About us


Sitni Sati was founded back in 1999 and quickly became recognized in the field of VFX software development. Innovative ideas and extensive research of the natural phenomena resulted in FumeFX, praised as one of the fastest and most flexible CG fluid dynamics simulation systems.


Our dedication to constantly improve the software and usage of the latest technology available helped to narrow the barrier between reality and CG imagery. Sitni Sati software was used in films like Thor, Suckerpunch, Skyline, 2012, Percy Jackson and the Olympians, X-Men: Wolverine, Iron Man, Armageddon, Matrix Reloaded and more.


When AfterBurn was released in 1998, it became a huge hit and was immediately considered the de facto standard for volumetric particle effects for Autodesk 3ds Max. It was initially used to help blast Bruce Willis into space in Armageddon, and over the years has helped companies like Computer Cafe, Blur, Uncharted Territory, Tigar-Hare, Digital Dimension and countless other facilities create stunning smoke trails, dust and explosions in their work. It also opened the doors to other companies who had never owned 3ds Max before, but bought copies of Max and AfterBurn solely to render out these gorgeous effects in that core product.

Eight years later, FumeFX 1.0 was released upon the world for 3ds Max and it was the first commercially available gaseous fluid dynamics simulator for 3ds Max. It is a powerful fluid dynamics engine designed for the simulation and rendering of realistic fire, smoke, explosions and other gaseous phenomena. Its versatility, robustness, and intuitive workflow made it a perfect solution for even the most demanding tasks in the computer graphics industry. Designed for use by visual effects artists, game developers, and visualization professionals who demand the utmost in realism, it is unrivalled in its ability to achieve the nuances and complexity of fluid gas behavior.


Within a few months after FumeFX 1.0 release, it was praised as one of the fastest and most flexible CG fluid dynamics simulation systems available on any platform - capable of producing completely photorealistic visuals of smoke and fire that interacts with the entire scene. FumeFX also takes advantage of the mental ray(tm) and Arnold rendering technology so that vfx houses with vast render farms can quickly render out fire that creates scene lighting. Never before have 3ds Max and Maya artists had such sophisticated tools to help offer their clients this sort of amazing output.


One of our goals is to provide premium support to all our customers around the globe. Users know how much a quick response time can be valuable when you're on the short deadline. We hope you will enjoy using our software the same way as we enjoy making it.
